What is a Remap, and what is a tuning box/chip?
A remap or ‘Tune’ is a modification to the cars ECU (Engine Control Unit). By Which it changes the parameters of both fuel and boost at various points to improve power and or fuel economy.
Our diesel tuning box provides very similar modifications to the fuel and boost systems. However instead of modifying the cars ECU software our unit plugs directly into the existing wiring looms. This enables the tuning box to modify the signals from the ECU in real time meaning that if the tuning box was to be removed, your cat returns to standard.
So which is better?
Customers often ask us why they should pick a tuning box over a remap or vice versa: we would like to give you the unbiased facts so you can make an informed decision.
The most important point to make is: not all diesel tuning boxes are the same. Similarly not all remaps are the same. Which one is right for you is entirely dependant on your personal requirements.
Both high quality diesel tuning boxes and high quality remaps can give very good results, improving power and toruqe, reducing turbo lag and improving fuel economy (MPG).
Unfortunately there are many companies out there which offer poor quality remaps and possibly even more companies which offer poor quality diesel tuning boxes, both of which offer a combination of poor performance and potential for damage to your vehicle.

Presuming that you are comparing products of similar quality, our comparison is as follows:
|Remaps||SW Diesel Unit|
|Must be carried out in an area local to the remapper. Not only does this mean that it’s often a long drive to have the work carried out, it also means another lengthy drive if problems occur. I.e. if the manufacturer flashes the ECU during servicing it would be lost.||Our unit can be delivered by post and fitted by the customer. They are supplied with full and comprehensive instructions and an installation video is available on the website to assist you with the process. If you decide that you are not 100% happy, return the unit in 28 days for a full refund.|
|Remaps are a permanent install. They cannot be removed when selling the vehicle or if you wish to have your vehicle serviced by the manufacturer. Once installed there is no adjustment or any way of switching it off.||You can easily remove our unit. If you were to sell your vehicle, it can be either fitted directly to a replacement vehicle or sent back to us for reprograming. Once our unit has been removed your vehicle returns to standard. There are also 45 adjustments to suit every individual’s needs.|
|Remaps will, as with all modifications, void warranty. They cannot be hidden in the software as claimed by some.||Tuning boxes, as with all modifications, can and will void warranty. It can be removed before servicing by the manufacturer so to keep your warranty intact. Undetectable when removed.|
|The safety parameters of the ECU are removed. They control fuel pressure and injection timing this means that they must run vey high boost pressures to keep the AFR (air fuel ratio) correct.||Our tuning boxes don’t raise and parameters above the recommended maximums by any manufacturer. Because we control both fuel and air it means we can keep your AFR’s correct in turn looking after your all-important EGT’s.|
|Often come with DPF or EGR delete’s. This maybe legal for off road use but may land you a sizable fine on highway use. Not only that your car insurance will be void as you have tampered with emission control.||As we keep the AFR’s correct it means we are DPF compatible. You should notify your insurance company of the install.|
